--- Comment #10 from Hajimu UMEMOTO <ume at FreeBSD.org> ---
After some discussion with hrs@, I think supporting the v4mapped address by
getaddrinfo(3) itself doesn't related to security.
And, the destination address selection didn't work against the v4mapped
address.
So, I re-made the patch:

    https://people.freebsd.org/~ume/getaddrinfo-v4mapped-20151213.diff

If there is no objection, I'll commit it.
